Abstract

The development of transportation technology triggers the presence of environmentally friendly vehicles such as electric cars. This car is also developed as a learning medium in vocational education. This article discusses the manufacture of the front of the electric car and its testing. Electric cars use electric motors as the main power source, with energy from batteries. This project designs and builds the frame structure of the front of the electric car focusing on the steering, suspension, and braking systems. The methods used include literature study, discussion, planning, design, workmanship and testing. Before operation, tests were carried out on the suspension, steering and braking systems. The results of the suspension test without load obtained data on the shaft length of 40 mm, with a load of 60 kg the shaft length of 25 mm and with a maximum load of 200 kg the shaft length of 2 mm. The steering system test produced a turning radius of 2 meters at a steering angle of 30 ° and 2.5 meters turning radius at a steering angle of 40˚. Tests on the braking system show that the braking distance is 10.05 m long with a stopping time of 4.3 seconds at a speed of 26.3 km/h, a braking distance of 8.74 m long with a stopping time of 3.2 seconds at a speed of 16.7 km/h, and a braking distance of 4.66 m long with a stopping time of 1.4 seconds at a speed of 8.1 km/h.
